DropDownList Control problem

Hi
I am using predefined membership and roles managemant approach
characteristic for framework 2.0  

Basic idea is that we select some value from DropDownList which
represents a role and we get all users for selected role.
This works and that is not a problem.

Problem is in DropDownList control...

I am using select value as follow:
string roles = DropDownList_Roles.SelectedValue;

Recieived items
---------------------------------------------------------------------------
        DropDownList_Roles.DataSource = Roles.GetAllRoles();
        DropDownList_Roles.DataBind();

For e.g. if I get following vales:
ABC
AAA
CCC
RRR
FFF

What is wrong?
-----------------------------
Whatever I select, I always getting first value, in this case value
ABC.

Thanks for help.

Mike

RE: DropDownList Control problem

It looks like you are populating your dropdown in Load event, but do not 
check IsPostBack property. Ensure that your dropdown is only populated when 
this property is false
